A discharge pipe .24 is threadedly mounted .at 25- in the body 10 and. has a passageway 26 communicating with. the common valve upper end of the passageway 26. A passageway 34 in the valve stem 29 has ports35 in communication with the common valve'chamber 23. A check valve plunger 36 has a tapered upper end'37 which engages the valve seat 38 of the valve seat bushing '39 appropriately fixed in the counterbore 40 of the thumb knob 30 of the valve stem 29..A compression spring 41 within the valve stem 29 normally yieldingly urges the check palms 42 and forefingers 43 of the hands, the air shuttling back and forth between the bellows chambers Hand 20,

To utilize the device as a pump to discharge air underpre'ssure but through the hose 27, the valve plunger 29 is screwed outwardly so as, to open the-common valve chamber 23 to communication with the passageway 26. Both bellows l5 and 16 are squeezed and released simultaneously to discharge air pressure through the hose 27 andthen take in air through the relief check valve 36.
